Having just purchased a Naish 2011 Park in excellent barely used condition, I am hoping to find a way to get rid of the minor brown stains that appear in the white sections of the Dacron canopy.
Previously we have removed black mildew stains from an floatation vest by soaking the vest in cold water and an Australian product called 'Nappy San'.
After a 24 hour soaking the stains required mechanical removal using a stiff bristled floor brush and some serious elbow grease. It took two days but eventually the stains were removed.
I do not know if the same method will work on the Dacron. Also I am concerned at soaking my entire Naish kite in a foreign chemical like 'Nappy San'.
Any suggestions or constructive criticism would be greatly appreciated.

the slight brown stains would be panel leaching from the darker colours sitting on the white when wet.

meh all my kites have some sort of leaching, they all get it, dosen't effect the way it flys just cosmetic.

foreign chemical to the kite and an australian brand, do you really need that comment Craig66?

dorothyinste is it on the dacron(leading edge and re-inforcements) or on the dynacote (main canopy) generally if its on the dacron leading edge or re-inforcements there is minimal to no chance of getting it off as once the colour gets into the fibres then its there to stay, if its on the dynacote(main cnaopy) then it should be a little easier as the coating on the material makes it harder for stains to get to the fibres, try soaking and gently wiping with a cloth in soapy water, as for the nappy san id be wary as it contains a bleach that could have an effect on the stitching strength,
hope it helps.

I wouldn't worry about trying to get the stains out of your kite. All kites get marks like this and they won't affect the longevity of the kite. Besides, I bet you can't see them when the thing is 24m in the air!

Be more concerned about sand in the kite, especially where the canopy meets the leading edge. Sand in here can abrade the canopy over time.

There is a product called 30 seconds (Bunnings may sell it)

I'm told it works, let us know if it does.

yeah i've tried a range of cleaning products like stain removers, mould removers etc, to no avail. In the end I was more concerned that I would remove the kites protective UV layer.

All you can do is make sure your kite is dry when you put it away.

Don't use nappy san on a kite
And especially don't use any mould remover products on a kite!
You will destroy the fabric and ruin your kite. The stain is most likely color transfer not mold!
Avoid pack up wet kites and stuffing them in a bag, if you get the kite wet lay it out somewhere at home and let it dry, rinse in plain cold fresh water if you must, but even thats not recommended. Salt water prevents mold.

Do you just want to be different? Every kite on the east coast has light brown stains on the white canopy sections after the summer we've just had. I've never thought of trying to actually remove them, but I'd say soap & water is about as extreme as I'd go.

Did some.kite maintenance today on a kite that I just repaired the trailing.edge, the canopy had a large dark rust stain on it. Looked on the net and found that lemon juice and salt mixed together removes oxidsed iron (rust).

Cut a lemon in half and smeared it on the stains and then sprinkled salt on and rubbed it in a little and left it in the sun for a while. Came back 30 min later and.it looked substantially lighter, reapplied another 2 times and it.is virtually gone.

Bleach it.

Whilst your at it chuck your lines in to makes them whiter than white.

Alternatively take it to the laundrette chuck it in an industrial washer.
